JEAN BAPTISTE DAUDELIN AND EUSEBE H. DAUDELIN, OF FALL RIVER, MASSACHUSETTS.

SHUTTLE.

To all whom it may concern:

Be it known that we, JEAN B. DAUDELIN and Eusnnn H. DAUDELIN, citizens of the United States, residing at Fall River, county of Bristol, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.

This invention relates to shuttles and particularly to that type of shuttle known as the hand threader in which the thread is drawn through a tortuous passage intoits ultimate line of delivery. As is well illustrated by the art, there has been a constant effort to secure a shuttle of this type which would be completely satisfactory. \Vhile shuttles have been produced which would give at least fairly satisfactory results in operation they have for the most part been only producible at a cost which rendered their substitution slow and their use expensive.

It is the object of the present invention to produce a hand threading shuttle which will not only be positive in its threading and safe against the escape of the thread, but, shall be strong and capable of production at a low price. This we have accomplished through the substitution of a guiding and trapping structure for the bushing, with which most of our former patents have dealt. The construction of these parts and their operation will be more fully described in the specification which follows:

In the drawings we have shown as an illustrative embodiment an arrangement which we find well adapted to practical use and also a modification which illustrates still further the application of the principles involved.

Throughout specification and drawings Specification of Letters Patent.

1, and Fig. 7 is a side elevation of the modified form shown in Fig. 6.

1 is a shuttle having the usual bobbin chamber 1 in which a bobbin 2 ismounted on a spindle 3.

4 is a transverse plate longitudinally disposed in a delivery passage. The plate 4 has centrally of its forward edge a notch 5 from which an incline runs up to a point 7 which may be upturned, as shown, to secure a slight bearing in the shuttle body, if desired. The plate 4 is slotted near one end, as indicated at 15.

9 is a second plate longitudinally disposed in the shuttle but at right angles to the plate 4. The plate 9 has a notch 11 at one end. This notch is preferably formed in a general triangular shape with rounded corners and a restricted outlet. At one side of the plate 9 it is curved up toward the outlet to give a gradually rounded edge along which the thread may run in entering the recess 11, while on the opposite side of the outlet is a projection 14 which acts as a stop to throw the thread into the recess 11. On the opposite edge of the plate is a projection 10 which fits within a corresponding recess in the rear edge of the plate 4 so as to lock the two plates together. Thus, when the plates are inserted, as shown in Fig. 4, the plate 9 may be held by the screw 12 and thus at the same time the plate 4 will be locked in place. The open mouth of the plate 9 extends through the plate 4 so that the recess 11 opens on the opposite side of the plate 4.

In the form of the device shown in Figs. 1 to 5, inclusive, a threading slot 6 is cut forward so as to enter the forward part of the transverse delivery recess 8 and in this position it passes around the forward end 7 of the plate 4. In this form of the device the thread in passing through the slot 6 would at once pass over the forward end 7 of the plate and on account of the incline from the notch 5 to the point 7 the thread would be worked back to the notch 5 which is its proper position in delivery. Meanwhile, in traveling back along the incline toward the notch 5 the outer end of the thread 2 is brought back under the plate 7 until it strikes the rounded forward end of the plate 9 up which it travels until its detlection through the slot 15 and finally striking the stop 1% is forced down into the delivery notch 11. hen in this position the thread guided between the notch 5 and the notch 11.

In the modified form, shown in Figs. 6 and 7, the guiding slot 6 enters the transverse delivery recess 8 to the rear of the point 7 of the plate 4;. The plate at in this instance is positioned centrally of the passage S but has its point 7 upturned and projecting within a recess or hollowed out portion in the upper wall of the passage 8 so as to be covered. In passing this point the thread is deflected around the point passing through the recess which with the point acts as aguard against its return.

hen the thread is drawn down through the slot (3 it first strikes the upper side of the plate A: and is drawn along by a forward movement until it is deflected by the tip 7 After passing this point it may be drawn back by a rearward motion, as described in connection with the form first set forth. During this rearward passage the thread runs back to the notch 5 and the outer end of the same ultimately is located in the notch 11. In both instances it is to be noted that the slot (3 or (3 emerges just behind a shoulder (3 at the end of the bobbin chamber. The mouths of the threading passage 6 and 6 are, therefore, covered so that in addition to the other locking of the thread the entry of the thread through the slot by ballooning is prevented.

Various modifications may be made in the operation and structure of our device, all without departing from the spirit of our invention if within the limits of the appended claims.

lVhat we, therefore, claim and desire to secure by Letters Patent is 1. In a shuttle of the class described having a bobbin chamber, a transverse delivery opening, and a threading slot leading into said delivery opening, av slotted plate longitudinally disposed in said opening, a second plate in said opening and located longitudinally thereof but at right angles to said first named plate, said second plate having a recessed end extending through the slot in the first named plate, whereby the mouth of said recess opens on the opposite side of the first named plate.

2. In a shuttle of the class described having a bobbin chamber, a transverse delivery opening, and a threading slot leading into said delivery opening, a plate longitudinally disposed in said opening and having a forward notch disposed centrally of the shuttle and a longitudinal slot near one side of the shuttle, a second plate at one side of said opening and located longitudinally thereof but at right angles to said first named plate, said second plate having a narrow mouthed recess in. its end, said end extending through the slot in the first named plate, whereby the mouth of said recess opens on the opposite side of the first named plate.

8. In a shuttle of the class described, a plate having a notch centrally disposed on one of the edges and a slot near one end, and a second plate having a notched end, the notched end of said plate loosely entering the slot of said plate to form a thread trap.

at. In a shuttle of the class described having a transverse delivery opening, a longitudinal tongue having a slott-herein and an upturned tip at its forward end, said tip being covered by a recess in the shuttle body but leaving a. passage on each side of said tongue and a thread trap consisting of a plate having a forked end projecting through the slot of said tongue.

In a shuttle of the class described having a transverse delivery opening therein, a longitudinal tongue having a slot, said tongue located in said opening and having a thread passage on each side of it and a forked thread trap consisting of a plate having its open end projecting through the slot in said tongue.

In testimony whereof, we aifiX our signatures in presence of two witnesses.
